The parameter type of q in function z() should be a 'char *', not a
'char **'.
Added to CSILENCE -Wno-implicit-int.
Note that if including files for abs(3), strlen(3) or other functions
implicitly declared the program will not work (or at least it won't work
if at least one of them is #included?).
Now allows for 'q' to exit the maze. This is to be a bit more intuitive
at least for those who use the alt version, which is not the recommended
version to try first nor should it be. This change is not in the
original nor should it be.
The alt version can be more at home for those familiar with vi(m) (it
certainly is for me): instead of 'f' for forwards, 'l' for left and 'r'
for right it is now 'k', 'h' and 'l' respectively. The program does not
allow one to go backwards so this was not touched but if it did it would
have been 'j': because we vi(m) users are strange :-)
